NAME

SYNOPSIS

DESCRIPTION

Linux supports different execution domains, or personalities, for each
process.
Among other things, execution domains tell Linux how to map
signal numbers into signal actions.
The execution domain system allows
Linux to provide limited support for binaries compiled under other
UNIX-like operating systems.

If
persona
is not
0xffffffff, then
personality()
sets the caller's execution domain to the value specified by
persona.
Specifying
persona
as 0xffffffff provides a way of retrieving
the current persona without changing it.

RETURN VALUE

On success, the previous
persona
is returned.
On error, -1 is returned, and
errno
is set appropriately.

ERRORS

EINVAL

The kernel was unable to change the personality.

CONFORMING TO

personality()
is Linux-specific and should not be used in programs intended to
be portable.
